Hello @Lavenda
Thank you for reaching out to community
Can you please confirm what is the heap assigned to CM server? You can check the same in /etc/default/cloudera-scm-server
Also, do you see JVM pauses in /var/log/cloudera-scm-server/cloudera-scm-server.log.
If you see JVM pauses in the above logs try increasing the heap for CM server and restart the cloudera-scm-server service (systemctl restart cloudera-scm-server)
# cat /var/log/cloudera-scm-server/cloudera-scm-server.log | grep -i "Detected pause in JVM"
